Abstract

Abstract

In this study, experimental investigations on the liquid's explosive dispersal under different shell constraints were carried out, effects of shell constraints on the early characteristics of the flow field were discussed, and the mechanism for liquid state transition and breakup was analyzed and compared with the numerical simulation. The results show that cavitation occurs in the liquid when the rarefaction waves reflects on the shell. The stronger the shell constraint, the greater the delay of the cavitation that emerges and the closer to the center where the cavitation is located, and the earlier the explosive product mixes with the liquid on the nearby interfaces.
